An acinus (/ˈæsᵻnᵻs/) (plural, acini; adjective, acinar [/ˈæsᵻnər/] or acinous) refers to any cluster of cells that resembles a many-lobed "berry", such as a raspberry (acinus is Latin for "berry"). The berry-shaped termination of an exocrine gland, where the secretion is produced, is acinar in form, as is the alveolar sac containing multiple alveoli in the lungs.
